摘要： A hydrodynamic bearing assembly includes a sleeve rotatably supporting a shaft, a thrust plate housing portion extending to an upper side of the sleeve in an axial direction so as to house a thrust plate, and a stopper ring housing portion stepped in an upper side of the thrust plate housing portion in the axial direction and housing a stopper ring for fixing the thrust plate. The stopper ring protrudes from the stopper ring housing portion such that an outer circumferential surface of the stopper ring has a larger height than an inner circumferential surface of the stopper ring housing portion.

摘要： Disclosed herein is a spindle motor which is capable of more easily controlling an axial gap and levelness between the thrust plate of a rotating shaft and a sealing cap. The spindle motor includes a rotating shaft having a thrust plate which is perpendicularly inserted into the upper portion of the rotating shaft. A sleeve accommodates the rotating shaft and rotatably supports the rotating shaft. The sleeve is secured to a plate. A sealing cap is secured to the sleeve through laser welding in such a way as to face the upper surface of the thrust plate. At least part of the sealing cap is stepped towards the thrust plate to correspond to a degree of deformation occurring during the laser welding.

摘要： A spindle motor having a hydrodynamic pressure bearing includes a stator, a rotor, and a dynamic pressure generating unit including a sleeve having an upper plate disposed opposite to the rotor and at least one thrust dynamic pressure groove formed either at the upper plate of the sleeve or at the rotor. Inside width from a neutral radius to an innermost radius of the thrust dynamic pressure groove is larger than outside width from the neutral radius to an outermost radius of the thrust dynamic pressure groove such that the neutral radius is biased to the outside of the thrust dynamic pressure groove. Dynamic pressure at the inside width of the thrust dynamic pressure groove is higher than dynamic pressure at the outside width of the thrust dynamic pressure groove such that fluid supplied into the thrust dynamic pressure groove is guided to the outer diameter side.
